.NET调用存储过程
用的是三层，实现注册功能。
这是DAL的SQLHelper

C# code

public static int ExcuteNonQuery(string sqlcmd, SqlParameter[] Parameter)        {            SqlConnection conn = new SqlConnection(SqlConn);            if(conn.State!=ConnectionState.Open)            {                conn.Open();            }            SqlCommand cmd = new SqlCommand();            cmd.Connection = conn;            cmd.CommandText = "st_register";            cmd.CommandType = CommandType.StoredProcedure;            if (Parameter != null)            {                foreach (SqlParameter item in Parameter)                {                    cmd.Parameters.Add(item);                }            }            return cmd.ExecuteNonQuery();        }

BLL层中的注册功能

C# code

public int CreateStudent(M_Student m_student)        {            return SQLHelper.ExcuteNonQuery("st_register", new SqlParameter[] {             new SqlParameter("@uname",m_student.Uname),            new SqlParameter("@password",m_student.Password),            new SqlParameter("@tel",m_student.Tel),            new SqlParameter("@sex",m_student.Sex),            new SqlParameter("@address",m_student.Address)            });        }

创建的存储过程

SQL code

create procedure st_register@uname varchar(50),@password varchar(50),@tel varchar(50),@sex bit,@address varchar(50)asinsert into Stu(uname,password,tel,sex,address)values(@uname,@password,@tel,@sex,@address)

为什么每次运行注册的时候会有：“超出了存储过程、函数、触发器或视图的最大嵌套层数(最大层数为 32)。”

[解决办法]
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go

ALTER procedure [dbo].[st_register]
@uname varchar(50),
@password varchar(50),
@tel varchar(50),
@sex bit,
@address varchar(50)
as
insert into Stu(uname,password,tel,sex,address)values(@uname,@password,@tel,@sex,@address)



go
--go一下
[解决办法]
死循环了，你把BLL中的参数写到DAL中去，直接调用DAL函数就行了
